That's what I was trying to avoid.  In the long run you will have
two separate areas but the load of the mirroring is stretched out
over time.  Probably I'm just still living in modem times...

That might help a lot.  If every package dir only contains the latest
versions you would have less than half the size.  The only problem
would be that you have to grep the setup.hint files and remove
potential version information.
